I really don't understand this. We're *NOT* proposing this patch as an
underhanded way of preempting the discussion of whether/how replication
identifiers are going to be used. We're proposing it because we
currently have a need for the facility and this will reduce the number
of patches we have to keep around after 9.5. And more importantly
because there's several other use cases than our internal one for it.

To settle one more point: I am not planning to propose BDR's generation
of replication identifier names for integration. It works well enough
for BDR but I think we can come up with something better for core. If I
had my current knowledge two years back I'd not have chosen the current
scheme.
